2SB1697T100

Single Bipolar Transistors Overview

The 2SB1697T100 is a PNP silicon small signal bipolar junction transistor manufactured by ROHM Semiconductor. It features a maximum collector current of 3A and a collector-emitter breakdown voltage of 50V. The device utilizes the MPT3 surface-mount package, which corresponds to the SOT-89-3 form factor with three terminals. Key electrical specifications include a minimum DC current gain (hFE) of 82 and a maximum operating temperature of 150°C. The component is designed for low saturation voltage performance, making it suitable for power switching applications.

Single Bipolar Transistors Feature Summary

• Low saturation voltage characteristics for efficient power switching
• High DC current gain stability across operating ranges
• Complementary pairing capability with specific NPN counterparts

Single Bipolar Transistors Applications

• General-purpose power switching circuits
• Driver stages in motor control systems
• Complementary output stages in audio amplifiers

Single Bipolar Transistors Procurement Notes

Verify the exact ordering suffix against the manufacturer's latest datasheet to ensure correct packaging and tape specifications. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the MPT3/SOT-89-3 footprint matches the target PCB design before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when a PNP transistor with 3A continuous current capacity and 50V voltage rating is required in a compact SOT-89-3 package. Consider its complementary relationship with the 2SC4672 NPN transistor for push-pull configurations. Evaluate thermal management requirements based on the 500mW power dissipation limit in the specified package.

Single Bipolar Transistors Part Context

This part belongs to ROHM's lineup of high-current small signal transistors designed for general-purpose applications. The 2SB1697 series is engineered to provide reliable performance in consumer electronics and industrial equipment where space-constrained power switching is necessary. It serves as a standard replacement for legacy components requiring similar electrical characteristics in a modern surface-mount format.

Single Bipolar Transistors Replacement Considerations

The 2SA1797 is documented as a complementary pair partner rather than a direct pin-compatible substitute. Verify electrical parameters such as hFE and VCE(sat) against the original design requirements before substituting with other 3A PNP transistors in the SOT-89-3 package.
